'One Finger Death Punch 2' will pummel its way into your heart

‘PUBG’ arrives on mobile in the US

NintendoWare Weekly: Brain Age demo, Super C

The new Brain Age: Concentration Training may make you feel terrible about math, or it may increase your brainpower. The only way to find out which of the two (or how much of each) is to get the demo, available on 3DS eShop today. Also on 3DS today is a surprise Virtual Console release, the Contra sequel Super C., and an eShop release of the launch game Ghost Recon: Shadow Wars.

Wii U already had a couple of off-schedule additions this week. If you missed them, The Cave went up Tuesday along with its release on other platforms, and Balloon Fight is on sale now for a pittance.
